Alloy 825 Industrial Fire Survival Cables

Mineral Insulated Alloy 825 fire-proof wiring units and cables are made up of a Nickel or Nickel-clad copper conductor embedded in a compacted Magnesium oxide (inorganic) insulant inside an extremely high performance Alloy 825 metal sheath.

The inorganic nature of the construction enables the cables to operate at high temperatures for long periods of time in extremely harsh environments e.g. petro-chemical, reactor vessels and other applications where the integrity of the cable is most important.

Operating temperatures: 

  • Bare cable operating exposure: up to 670C
  • Max exposure temperature - Nickel conductors: upto 1350C
  • Max exposure temperature - Nickel clad copper conductors: upto 1200C
  • Cable with PVC or LSF covering: up to 105C

Cables can be joined by joints that also withstand direct fire temperatures. These have been tested to 1095C for 30 minutes without circuit failure.
